President Donald Trump is once again testing the boundaries of executive power on immigration with two new executive orders that are expected to face legal challenges. The new orders are significantly narrower than Trump's previous attempt to limit birthright citizenship, which ultimately reached the U.S. Supreme Court. The second targets so-called "birth tourism," aiming to prevent automatic citizenship for children born to women whom the administration believes traveled to the United States primarily to give birth.

The executive orders also renew debate over the scope of birth tourism.
